Cookie-cutting using Tiles

Tiling the export area involves exporting rectangular grids, or tiles, with a height and width that you specify. This may be useful for preparation of raw flight line LIDAR data into a project workflow.

Tiling is also a useful way to create rasters that can be built into raster catalogs representing elevations or slopes that you can access seamlessly. When tiling to raster files, valid values such as elevation, slope, hillshade, etc. are obtained all the way to the edge of the tile. This allows you to break large areas into smaller tiles while maintaining that the data be edge-matched, thus allowing you to use the rasters seamlessly.

How to Cookie-cut with Tiles

1. Open the LP360 Export Wizard by clicking the Export LIDAR Data command on the LP360 toolbar. The Export Wizard dialog will open.

   

2. Complete the first step required in the Export Wizard. See Export Format (Step 1 of 3) for instructions on starting the Export Wizard and completing the initial step.

3. On the Step 2 of 3 page, click Use Basic Extent. Follow the instructions in Using a Basic Extent to set up the parameters for a basic extent export.

   

4. Select the Cookie-cut into Regular Tiles checkbox. A frame will appear displaying information such as tile width and height.

   

5. Enter a Tile Width and Height (in map units), greater than zero, to define the size of the rectangular tiles. The File Rows and File Columns display fields will update as the width and height are changed. The Number of Files display field shows the number of files that will be exported for the export area using the specified width and height.

   

6. To buffer each tile, select the Buffer Tiles checkbox and enter a buffer distance (in map units) greater than zero.

   

7. Click Next to go to the next step in Export Wizard.
